The objective of this study was the study of tomato varieties tolerance to
Orobanch aegyptica. Seeds of 26 tomato varieties: cal-g, super-b, rio-s, super-y, super-h, shef, CH, earur-vf, supst-b, CH-falat, y-falat, SDR13128, falat111, hyb1509, primoear, calgn3, erur-111, FDT202, FDT101, primo, petoerCH, kingst, viva-100, primax, petorak, primato, together broomrape seeds were sown in pots in a controlled-environment greenhouse. The characteristics of tomato cultivars was evaluated after broomrape emergence and before fruit ripenning. The following characteristics were evaluated in tomato weekly: stem dry weight, root dry weight, leaf number, stem height, and stem diameter. The following characteristics were evaluated in broomrape: stem dry weight, root dry weight, stem number. In general, it was found that the most tolerant cultivar was Petorak with 6.94 % root weight, 28.61% stem weight, and the most sensitive cultivar was Primoearly with 79.64% root weight and 99.37% stem weight reduction. It is notable that broomrape showed minimum shoot number and shoot dry weight as grown together Petorak cultivar
